ORIGINAL: Time Pilot

And get a battery rated for max amps of your system. One of the myths that I had to unlearn was that you can cut amp draw by using a lower throttle setting. ESC's work by either being on or off for a different percentage of the time. For example, the circuit may only be 'on' for 10% of the time at low throttle, but while on, it's drawing the max current during that time for that particular system.

Time Pilot, I can see your reasoning, but why does my clamp metre show these higher amps at lower throttle positions - is it just a matter of the current being averaged over the sample time?

And does it matter? Surely if an ESC is rated to 20A they mean 20A for 100% of the time. Or is it a cell chemistry thing?
